As I come encounter historical records in my work I add note the people and places connected to West Feliciana Parish and them to this spreadsheet to refer back to later. It's a tiny drop in the bucket so far but if it helps one family find lost relatives then I consider it valuable.
There are tabs at the bottom: Places, Enslaved Persons, Freedman's Record Index, Probate Record Index, Business and Occupations.
It's not perfect by any means, but it's what I use to capture information I come across that might be of use to someone else researching in this parish.
